220-1201 Exam Dumps - CompTIA A+ Core 1 Exam (2026)

B. USB-C:

USB-C is a versatile connector that supports charging, high-speed data transfer, and the ability to send audio and video signals (e.g., DisplayPort over USB-C).

It is used by most modern mobile devices and laptops because of its fast transfer speeds and power delivery capabilities.

Incorrect Options:

A. Lightning: Lightning is proprietary to Apple devices and does not natively support video output.

C. MicroUSB: MicroUSB is outdated and does not support video output.

D. MiniUSB: MiniUSB is an older standard and does not support modern features like video output or fast charging.

Key Takeaway: USB-C is the most versatile connector for charging and transferring data, audio, and video.

Adocking stationconnects to a laptop’sproprietary port or USB-C/Thunderbolt, providing access tomultiple additional ports(USB, Ethernet, video, audio, etc.). It allows users to transform a laptop into a full desktop workstation.

Option A (NFC adapter):Used for short-range communication, not port expansion.

Option C (Port replicator):Similar to a dock but usually less powerful and often lacks charging or video output.

Option D (USB dongle):Adds a single function (like Wi-Fi or storage), not full port expansion.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.4: Given a scenario, configure settings and use cases for laptops and mobile devices.

===========

Changing the page orientation(e.g., fromportrait to landscape) allows wider columns to fit on one side of the page. This maintains readability while continuing to use duplex printing.

Option A:Disabling duplex defeats the goal of printing on both sides.

Option B:May help, but could make the document harder to read if the font is too small.

Option D:Unlikely to resolve formatting issues related to layout and dimensions.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 3.7: Given a scenario, troubleshoot common printer problems.

Abulging tablet casingis a classic sign of aswollen lithium-ion battery, often caused by age, overheating, or overcharging. This is adangerous condition, as swollen batteries can rupture or catch fire. It also explains why the tablet only works when plugged in the battery is no longer holding a charge.

Option A:Power supply issues wouldn’t cause physical bulging.

Option B:A bad charge port wouldn’t cause screen damage or physical distortion.

Option D:A broken screen could cause display issues, but not the bulging chassis.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.4: Given a scenario, configure settings and use cases for laptops and mobile devices.

===========

A failing CPU fan may make unusual noises (including clicking) and, if it is not cooling the CPU, the system will quickly overheat and shut down to prevent damage.

From CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 – Troubleshooting hardware problems:

“Overheating due to a failed or obstructed CPU fan can cause frequent shutdowns. Loud noises are a sign the fan should be checked first.”

============

The correct answer is D. Decreased burn-in.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Display Technologies:

Mini-LED displays use an array of tiny LEDs as a backlight for LCD panels.

Unlike OLED displays, which are susceptible to burn-in (permanent image retention when static content is displayed for long periods), mini-LEDs reduce the risk because the pixels themselves do not emit light individually and are less prone to permanent image retention.

Why the other options are incorrect:

A. Increased contrast: OLED typically provides better contrast because it can turn off individual pixels completely.

B. No backlight: Mini-LEDs still use a backlight, whereas OLEDs do not.

C. Improved viewing angle: OLEDs generally offer wider viewing angles than mini-LED LCDs.

Looking at the network configurations and outputs from both PCs and servers, here are the possible issues and solutions:

1. PC 1

Issue: The IP address for PC1 is 192.168.1.1, which conflicts with Server 1 (which also uses 192.168.1.1).

Solution: Change the IP address on PC1 to a unique one within the range, like 192.168.1.3.

2. PC 2

Issue: PC 2 is configured with 192.168.1.2, which conflicts with Server 2 that has the same IP address.

Solution: Update the IP address on PC 2 to something unique, like 192.168.1.4.

3. Server 1

Issue: The IP address for Server 1 is 192.168.1.1, which conflicts with PC1.

Solution: Since Server 1 and PC1 are using the same IP address, change one of them. For Server 1, you could change the IP address to 192.168.1.5.

4. Server 2

Issue: Server 2 is using the IP address 192.168.1.2, which conflicts with PC2.

Solution: Update Server 2 to use a different IP address, such as 192.168.1.6.

General Remediation:

The primary problem here is overlapping IP addresses, leading to connectivity issues. Each device on the network must have a unique IP address. After making these changes, ensure that all devices can communicate properly by testing the connection between devices and verifying they can access shared resources.

The correct answer is A. NFC (Near Field Communication).

According to the CompTIA A+ Core 1 220-1201 objectives under Mobile Devices, NFC is commonly used for short-range wireless communication between devices. In the context of mobile printing:

NFC-enabled printers allow a user to tap a mobile device (phone or tablet) to the printer to initiate a print job instantly without needing to configure Wi-Fi credentials or use cables.

This is particularly common in mobile-friendly environments like offices or public kiosks.

Why the other options are incorrect:

B. Hotspot: Provides an Internet connection, not a direct mobile-to-printer interface.

C. Infrared: Legacy technology largely replaced by NFC and Wi-Fi; rarely used in modern printers.

D. USB: Requires a wired connection, not suitable for sending a print job wirelessly from a mobile device.
